A quick look at the latest news out of the Big 12 from around the Rivals.com Network:

Big 12 North Practice Reports

Colorado: Junior Brian White had led the quarterback battle early in fall camp, but Sunday it was senior James Cox who was named the team's starting quarterback. White struggled in both of the team's fall scrimmages. Even though Cox didn't exactly wow anyone, he did complete 14-of-29 passes for 198 yards and no interceptions in the second scrimmage.

Iowa State: The Cyclones got a big boost this week. Offensive tackle Ahtyba Rubin finally joined the team in practice Monday. The 6-3, 315-pound junior college transfer was All-District last season for Trinity Valley College in Texas. Projected starting defensive end Kurtis Taylor is out for the season because of a knee injury.

Kansas: Freshman running back Angus Quigley suffered a very rare foot injury that will sideline him for the entire season. The injury was so rare that Kansas doctors did not know how to diagnose it and he is now under the care of the Miami Dolphins' orthopedic surgeon. Starting free safety Darrell Stuckey will not be ready for the start of the season.

Kansas State: Senior co-captain Greg Wafford is working hard to regain his starting left guard position, which is currently occupied by sophomore Matt Boss. Sophomore running back Parrish Fisher passed the conditioning test last Thursday but has yet to practice with the team as he continues to rehab his left knee.

Missouri: Senior defensive end Brian Smith has had his way with the Tigers' offensive line this camp. If he can perform at this level during the season he should be one of the top defensive ends in the conference. Sophomore Chase Daniel has locked up the starting quarterback job. In two scrimmages, Daniel is 31-for-40 for 372 yards and three scores.

Nebraska: Junior receiver Maurice Purify caught everything thrown his direction Sunday and had his way with the Nebraska corners. Senior linebacker Dontrell Moore is no longer part of the Cornhusker football program. The reason was not released but he had been academically ineligible for last year's Alamo Bowl.

Big 12 South Practice Reports

Baylor: Freshman Blake Szymanski ran the first team Baylor offense on Friday with starter Shawn Bell on the sideline. Chandler Dane led the second unit, and both Szymanski and Dane looked good over the weekend. Five former walk-ons were awarded scholarships this fall.

Oklahoma: Sophomore defensive back Reggie Smith is the definition of 'slash' at Oklahoma. A year ago, Smith started at safety and handled the Sooners' kick return duties. This season he has made the switch to corner, picked up the punt returning duties, and now he is adding another slash. Coaches have decided to line Smith up on offense in the slot for a number of plays this season.

Oklahoma State: The team had expected to get starting receiver Anthony Parks back at practice this week. Instead, the team learned that Parks' football career is over after doctors discovered he only had one kidney and recommended that he stop playing. Redshirt freshman Brady Bond has stepped up in practice this fall and is making a push to be in the two-deep rotation at left tackle.

Texas: Running back Selvin Young looks like he is in midseason form in fall camp. He is playing like a feature back, although he will share time with Jamaal Charles. Quarterback Colt McCoy continues to look like the front-runner for the Longhorns quarterback job, leading the offense to two touchdowns in his two series of the team's recent scrimmage. The team is developing some depth in the secondary thanks to the development of the true freshmen cornerbacks.

Texas A&M: The departure of William Morrissey was supposed to leave a major void in the team's depth at defensive tackle. Instead, it has cleared a spot for redshirt freshman Kellen Heard. Heard is a 6-6, 330-pounder who was a four-star recruit according to Rivals.com. Kickers Layne Neumann and Matt Szymanski missed all six of their field goal attempts in Saturday's scrimmage, with two of them getting blocked.

Texas Tech: Senior receivers Jarrett Hicks and Joel Filani have battled nagging injuries throughout camp. Receiver L.A. Reed looked good at the start of camp, but he too has missed significant time with injuries. All the injuries have opened the door for two freshmen. Edward Britton and Michael Crabtree have taken the opportunity to show coaches that they are going to be something special in Lubbock. Britton is a burner who moved from running back while Crabtree is your more prototypical receiver at 6-2, 208 pounds.
